Pork tenderloin is one of those weeknight heroes that can be insanely good, but only if you dodge its one classic flaw: overcooking. This recipe keeps things simple and bold. We build a quick spice rub, sear hard for those crisp edges, then finish in the oven so the inside stays blush pink and ridiculously juicy.

And because I am not letting you walk away with a dry dinner, we also make a fast pan sauce right in the skillet. It is bright, savory, and just buttery enough to make you pause mid-bite like, okay wow.

Why It Works

  • Juicy every time: We target 145°F with smart carryover and rest properly so the juices stay where they belong.
  • Big flavor, low effort: A pantry rub plus a 5 minute pan sauce does the heavy lifting.
  • Crisp outside, tender inside: High heat sear first, then gentle oven finish.
  • Flexible: Works with cast iron or stainless steel, and the sauce adapts to what you have.

Storage Tips

Cool it fast: Get leftovers into the fridge within 2 hours. For best texture, store the tenderloin as a larger piece and slice as needed. If you want it to cool faster, you can slice it first, just know it may dry out a bit more.

  • Refrigerate: Store pork and sauce in airtight containers for up to 4 days.
  • Freeze: Freeze sliced pork with a little sauce for insurance against dryness. For best quality, use within 2 to 3 months.
  • Reheat (best method): Add pork and a splash of broth or water to a covered skillet over low heat until warmed through.
  • Microwave tip: Medium power, short bursts, with sauce on top. Microwaves love to bully lean meat.

Leftover idea: Thin-slice and pile onto toasted rolls with mayo, mustard, and some quick pickles. Lunch solved.

Common Questions

What temperature should pork tenderloin be cooked to?

Cook pork tenderloin to an internal temperature of 145°F in the thickest part, then rest for 5 to 10 minutes. If you like a slightly pink, super juicy center, you can pull it at 140°F and let carryover heat bring it up close to 145°F as it rests. If you prefer it less pink, pull at 145°F.

Why is my pork tenderloin dry?

Usually it is one of three things: it was cooked past 145°F, it did not rest, or it was reheated too aggressively. Use a thermometer and pull it early rather than “just to be safe.”

Do I need to brine pork tenderloin?

Not required, but a quick brine helps if you have time. If you want to do it, dissolve 2 tablespoons kosher salt in 4 cups water, brine for 30 to 60 minutes, then pat very dry before seasoning. Salt brands vary, so if you prefer to measure by weight, use about 30 to 40 grams kosher salt (Diamond Crystal on the lower end, Morton closer to the higher end).

Can I use pork loin instead of pork tenderloin?

They are different cuts. Pork loin is larger and needs a different cook time. This recipe is written for pork tenderloin, the long, thin, very tender cut.

Can I make this ahead?

Yes. Season the pork up to 24 hours ahead and keep it uncovered on a plate in the fridge for a drier surface and better sear. Cook when ready.

What should 145°F pork look like?

At 145°F, pork tenderloin can be slightly pink in the center, and that is normal. It will look juicy, not raw. Resting finishes the job and keeps the juices where they belong.

I used to treat pork tenderloin like a fragile little thing that needed constant hovering. Turns out it just needed confidence and a thermometer. The first time I nailed it, I remember slicing in and seeing that perfect juicy center and thinking, wait, why have I been living like this. Now it is one of my go-to “I want a real dinner but I also want to sit down soon” meals. Sear hard, sauce fast, taste as you go, and suddenly Tuesday feels like you booked a table somewhere.
